On the direct stability assessment of parametric rolling with CFD : Preparation for the Second Generation Intact Stability Criteria [PDF]
, 2023 Parametric rolling is a phenomenon where a ship starts to uncontrollably oscillate with increasing amplitude. This is caused by the surrounding waves parametrically amplifying the naturally occurring small rolling motions. The phenomenon can be dangerous,
